On the good side, the back looks pretty good. I'd push the top shape of the scapula more, raise her hips and butt up, ease up on those waist wrinkles (ribcage?) and I think it'd shape up pretty nicely.

Scratches need to be in places where the metal will contact and rub against other things, so it'll mostly be on edges. You're overdoing it; looks more like someone took to the finish with some kind of super-solvent.

Adding dirt isn't such a big deal, take a look at the scope I linked above and you will see that the corners of the switches are all dirty. The main reason for this is the oil to keep the switches intact.

You placed the scratches too randomly, try to find some references of used scopes or from other games.

You should also put some fingerprints on it, they add a lot of realism and underline the used look of the scope. (There's a lot of brushes on deviantart )

I recently downloaded the 3ds Max trial, since i want to learn modelling, and i was wondering if anyone had any good tips?
Bloo have already helped on some points, but i feel stuck with the controls :P
Thanks.

Can't really give any tips about the controls, that's something you're just going to have to learn through using the program frequently, I really like how Max works though so it's worth it.

Tips regarding actual modelling? If you're starting from the very beginning watch Youtube videos on how to make very simple stuff, eventually you'll find that things start snowballing and your work quality will skyrocket.

Assuming you're not trolling, a part of the subdiv technique is the use of edge loops to control the shape of the model, it's like sculpting. If I were you I'd scrap that model, read up a shitton on it then have another bash at it when you understand it a little better.

Ok, but i didnt found any tutorial about that, so i didit alone looking in the menu, can you give me a good tutorial for Softimage Xsi?
